ABSTRACT:
Method and system for distributing prefragmented data processing loads in a fault tolerant system linked in a ring topology of disk subsystems and data processing nodes. The data processing load of the node under fault is shifted in one direction along the ring, and adjacent nodes in the same direction along the ring successively shift their entire data processing loads to their immediately adjacent data processing nodes. The adjacent data processing nodes in the non-shifted direction absorb increased workloads by one net data fragment each. Each successive data processing node away from the node under fault absorbs an increasing number of data fragments from its adjacent data processing node until the entire data processing load of an adjacent data processing node is absorbed.
